Extremely light: Titanium alloy weighs nearly half as much as steel and has a density of only 55.7%. High strength: Titanium alloy screws have a low weight but a high hardness, with a hardness of HRC 34–38. Safety and mechanical strength are still ensured even with the weight reduction. Moreover, titanium has a certain amount of bendability, which makes it an ideal material for cars, motorcycles, bicycle accessories, and other unusual applications. Corrosion resistance: Titanium material is capable of withstanding corrosion in a range of conditions, such as acid, alkali, water, dirt, and oil. Your car's safety and appearance are improved by its resistance to corrosion.

Q: Tool for measuring bolt dimensions.
A: Please use vernier caliper, micrometer and other tools to measure the bolt size unit
It is millimetres (mm).
Q: About the price.
A: If there is no special explanation, the price is the price of a bolt. Due to the particularity of titanium and processing technology, the price of titanium alloy products is relatively high.
Q: About the color difference of the products purchased at different times.
A: Due to the particularity of PVD and anodizing processing, each batch of products may have a little difference, not a quality problem.
